Description
Verfahren zur Herstellung von lichtempfindlichen Schichten auf beliebigen Unterlagen unter Benutzung von Diazoverbindungen von Aminonaphtholderivaten Es ist bekannt, daß sich Diazoverbindungen zur Herstellung von negativen und positiven Lichtbildern eignen. In Betrachtkommen hierfür besonders die Diazoverbindungen der Aminophenole und -naphthole, - da sie sich durch große Beständigkeit und Lichtempfindlichkeit auszeichnen. Für den Negativprozeß wurden besonders Diazosalicylsäuren und die Diazoverbindungen der Aminonaphthole (siehe Patentschrift 379 998) vorgeschlagen. In der Patentschrift 379 998 sind als solche die Diazoverbindungen der i - 2- oder 2. i-Aminooxynaphthaline oder deren Derivate genannt. Als Derivat ist die i-Diazo-2-oxynaphthali-n-4-sulfosäure angegeben.Process for the production of light-sensitive layers on any type of substrate using diazo compounds of aminonaphthol derivatives. It is known that diazo compounds are suitable for the production of negative and positive light images. This especially the diazo compounds of aminophenols and naphthols consider coming - as they are characterized by excellent resistance and sensitivity to light. For the negative process, diazosalicylic acids and the diazo compounds of aminonaphthols (see patent 379 998) have been proposed. In patent 379 998 , the diazo compounds of i - 2- or 2. i-aminooxynaphthalenes or their derivatives are mentioned as such. The i-diazo-2-oxynaphthalene-n-4-sulfonic acid is specified as a derivative.
Es wurde nun gefunden, daß man ausgezeichnete kontrastreichie Bilder mit dunklen Tönen erhält, wenn man die Diazoverbindungen von Aminonaphtholcarbonsäuren zur Herstellung der lichtempfindlichen Schichten auf einer beliebigen Unterlage verwendet. Diese Verbindungen fallen zwar unter die in der Patentschrift 379998 erwähnten Derivate, sie sind aber nicht ausdrücklich dort genannt. Mit den Diazonaphtholen oder deren Sulfosäuren erhält man wohl dunklere Töne, doch sind sie schlecht wasserecht und weniZ lichtecht. Die Diaz-osalicylsäuren geben nur rote, wenig kontrastreiche Kopien. Man kann die Aminonaphtholcarbonsäuren in saurer, -neutraler oder alkalischer Lösung auf die Unterlage, wie z. B. Papier, Cellulosefilm, aufbringen. Sauer gestellte Schichten bleichen im Licht aus.It has now been found that excellent, high-contrast images with dark tones are obtained when the diazo compounds of aminonaphtholcarboxylic acids are used to produce the photosensitive layers on any substrate. Although these compounds come under the derivatives mentioned in patent 379998 , they are not expressly mentioned there. With the diazonaphthols or their sulphonic acids one gets darker tones, but they are poorly waterfast and less lightfast. The diazosalicylic acids give only red, poorly contrasting copies. You can apply the aminonaphtholcarboxylic acids in acidic, neutral or alkaline solution to the substrate, such as. B. apply paper, cellulose film. Layers exposed to acid fade in the light.
Will man negative Bilder erhalten, so bringt man das sauer bestrichene Papier vor der Belichtung kurz in Ammoniakdampf. Ein derart behandeltes Papier gibt dann unter einer Vorlage, ebenso wie Papiere, die mit neutralen oder alkalischen Lösungen der Diazonaphtholcarbonsäuren behandelt worden sind, dunkle, tiefviolette bis blauschwarze Bäder, die, sich noch durch Zusätze von Metallsalzen zur Schicht oder durch Nachbehandlung mit Metallsalzlösungen im Tone und in der Haltbarkeit beeinflussen lassen. Doch zeichnen sich bereits die nur mit Wasser gewaschenen Bilder durch eine gute Lichtechtheit aus.If you want to get negative pictures, bring the sourly painted one Briefly immerse paper in ammonia vapor before exposure. A paper treated in this way gives then under a template, as well as papers made with neutral or alkaline Solutions of the diazonaphthol carboxylic acids have been treated to be dark, deep purple to blue-black baths, which, by adding metal salts to the layer or by post-treatment with metal salt solutions in the clay and in the durability be influenced. But the pictures, washed only with water, are already evident characterized by good lightfastness.
Weiter kann man, wie bereits bekannt, der lichtempfindlichen Schicht Kolloide, wie z. B. Gelatine"oder die Haltbarkeit erhöhende Stabilisatoren, wie z. B. Naphthalintrisulfosäure und andere, beifügen.As already known, the light-sensitive layer can also be used Colloids such as B. Gelatin "or stabilizers increasing the shelf life, such as z. B. naphthalenetrisulfonic acid and others, add.
Beispiel Man bestreicht oder tränkt Papier oder Film mit einer Lösung aus 1,6 Gewichtsteilen r-Diazo-'->-OXY-3-naphthoesäure und 2o Raumteilen verdünnter Natronlauge und trockne. Hierauf wird unter leinem Negativ belichtet und, naclidein das positive Bild gut sichtbar geworden ist, mit Wasser ausgewaschen. Man erhält ein blauschwarzes Bild auf reinweißem Grund, das durch Nachbehandlung mit Metallsalzen in mannigfaltiger Weise getönt werden kann; z. B. erhält man mit Kupf erlösungen neutrale, schwarze Töne.Example One brushes or soaks paper or film with a solution from 1.6 parts by weight r-Diazo -'-> - OXY-3-naphthoic acid and 2o parts by volume dilute caustic soda and dry. This is followed by exposure under a negative and, after the positive image has become clearly visible, washed out with water. A blue-black image is obtained on a pure white background, which is obtained by aftertreatment can be tinted with metal salts in a variety of ways; z. B. is obtained with Copper redeems neutral, black tones.
